Question

Two bodies of different masses m subscript a end subscriptand m subscript b end subscript are dropped from two different heights a and b. The ratio of the time taken by the two to cover these distances are

  1. a blank colon b  
  2. b blank colon a  
  3. square root of a blank colon blank square root of b  
  4. a to the power of 2 end exponent blank colon b to the power of 2 end exponent  

The correct answer is: square root of a blank colon blank square root of b


    h equals fraction numerator 1 over denominator 2 end fraction g t to the power of 2 end exponent rightwards double arrow t equals square root of 2 h divided by g end root
    t subscript a end subscript equals square root of fraction numerator 2 a over denominator g end fraction end root and t subscript b end subscript equals square root of fraction numerator 2 b over denominator g end fraction end root rightwards double arrow fraction numerator t subscript a end subscript over denominator t subscript b end subscript end fraction equals square root of fraction numerator a over denominator b end fraction end root
